Would you pay money to get a concoction of vitamins every month from Donald Trump? Hopefully you wouldn’t, but apparently some people did exactly that in the late 2000s and early 2010s, according to a new report from The Daily Beast. And guess what? A Harvard doctor tells the publication that the entire program was a comically inept scam.

“For several years in the late 2000s and early 2010s, Donald Trump encouraged people to take part in a pseudo-scientific vitamin scheme—all without expressing any concern about how it might potentially endanger people’s health,” The Daily Beast writes. “Through a multi-level marketing project called The Trump Network, the business mogul encouraged people to take an expensive urine test, which would then be used to personally ‘tailor’ a pricey monthly concoction of vitamins.”

Harvard doctor Pieter Cohen, who specializes in analyzing nutritional supplements, took one look at a 12-page monograph that the Trump Network provided to prove the scientific worth of its vitamin regimen and concluded it was a massive scam almost immediately.

“There is zero evidence that is actually doing what they say it was,” he tells The Daily Beast. “This is a scam, it’s a bogus program to make profit for the people who are selling it. It’s fantasy.”

Janet Helm, a nutritionist and registered dietitian, shares Cohen’s assessment of the validity of the Trump vitamin program, which she referred to as “mumbo jumbo.” She also says this is much more potentially dangerous than some of Trump’s other failed ventures such as Trump Steaks.

“If you want a steak or a wine with Trump’s name on it, that’s fine — but if you want to play around with your health and have someone try to sell you something because they think they need to sell you pills, that’s something entirely different,” she tells The Daily Beast.
